Someone found this quiver with surprisingly high values, although I'm unable to find a level 30 rare quiver on d3db.com

I'd like to know whether the level of an item affects the minimum/maximum rolls for the each attribute, a graph or table would be great.

Also, does the rarity of an item at a particular level increase the maximum number of attributes possible?

Given that the item's internal level (IIL) determines which affixes are possible, I'd like to know whether the IIL affects the minimum/maximum rolls for an attribute, a graph or table would be great.

For example, let's say items are able to get a pure +intellect affix from IIL 20, what's stopping you from rolling 250 at 20?

Is it a bell curve, which has shallower gradients with a higher IIL of the item?

Is it capped, dependant on IIL?

Do the min/max caps step up at certain IILs,though it's the same attribute? For example, IIL 20-40 is capable of 5-120, IIL 41-60 is capable of 20-320, ..., IIL 63 = 40-400
